I have though, for years, run a bottle of Techron through the fuel system at least twice per 10,000 miles. Have used Marvel oil in the past too. Don't see any need to change MY maintenance program now.

What I'm wondering is how often the OP changes the AMSOIL Nitrogen in his tires ...

Ooooohhhh, good one, I bet he uses Amsoil muffler bearing grease as well.

Final drive only/no oils

That's abuse and non-maintenance. Using 75W140 Severe Gear had nothing to do with it. I'd like to know what your basis is for claiming the use of heavy gear oil has caused problems. Lets see the stories and the evidence. As stated before, I've used Amsoil in all of my dozens of motorcycles and always used a heavier gear oil. No issues in 40 years. You were saying?

This bike is 10+ years old with 37,000 miles on it. At some time, this bike sat for a long time. The final drive is vented and will attract stuff; water, vapors and dust. The oil you changed out of it was most likely after bringing it home after a short test ride. Some one started off with a dry upper half of the final drive. Rusting and pitting and flaking into the oil you changed out.
These bikes NEED to be ridden! I see more seal failures from bikes that have low mileage for there age. The upper half of the seal goes dry and scores till lubed again.

Good Luck with the bike, but I see a main seal, transmission input seal and a final drive pinion seal in your future..it's not a thing about the oil you use, this bike sat and rotating things on dry seals will score them....
